Error above followed from both [cmake -DCMAKE_BUILD_TYPE=Release .] and [git checkout v0.5.3].Perhaps those tests are not important but seeing any error might put new users off? Also, it would be good to see the BUILD_UBUNTU.md suggest the same as the build instructions on the wiki - or vice versa. I guess for BitShares using -DCMAKE_BUILD_TYPE=Release is better than just cmake .

If that is present in 0.5.3 tag then it is mistake. This error has been fixed for a while on all other branches.

For making the build instructions consistent--go ahead and submit a pull request or edit the wiki.
